Laser Sheet Scanning Based Smoke Acquisition and Reconstruction
This paper develops a laser sheet scanning based technique for capturing and reconstructing sequential volumetric models of smoke.First,a dedicated setup is introduced as the laser sheet illuminator in horizontal scanning.To achieve an accurate acquisition,a signal synchronized scheme is added between the galvanometer and the high-speed camera.Then,with a laser sheet sweeping through the volume repeatedly,the illuminated smoke slices are captured.Each sweep of the laser records a near-simultaneous smoke density field.In next reconstruction procedure,through camera and laser calibrations,3D real positions of the pixels of captured images is calculated.Finally,these irregular smoke density fields are resampled by a 3D original Kriging interpolation algorithm and are reconstructed to regular smoke volumetric models.In experimental results,the fidelity of visualized smoke volumetric models reconstructed by our smoke modeling method demonstrates that our approach can make a good effect on realistic smoke modeling.
